Discina caroliniana

Gyromitra caroliniana, known commonly as the Carolina false morel or big red, is an ascomycete fungus of the genus Gyromitra, within the Pezizales group of fungi. It is found in hardwood forests of the southeastern United States, where it fruits in early spring soon after snowmelt. The fruit body, or ascocarp, appears on the ground in woodland, and can grow to massive sizes. The heavily wrinkled cap is red-brown in color, nearly spherical to roughly elliptical in shape, and typically measures 15 to 20 cm (5.9 to 7.9 in) tall and 6 to 13 cm (2.4 to 5.1 in) wide. The stipe is massive, up to 11 cm (4.3 in) thick, with a white felt-like surface. The brittle flesh is densely packed into the cap in convoluted folds that form internal locules....read more on Wikipedia.
